A function that allows you to change the layout of the interior of the dishwasher - in particular the height and sometimes the width or layout of the upper basket. Most often it is a height-adjustable top basket with 2-3 fixed positions or a continuous slide. This makes it easy to create more space for taller glasses, carafes or pots, or to fold/lift parts of the wires (called spikes) for stable storage of different shaped dishes.
